Error in Embedded Visualforce Page Flow
I have created an embedded Visualforce page to replace the "New" button on the Account object. The page calls a Flow, in which the users is able to check off checkboxes. The finish location of the Flow is designed to be 1 of 2 locations, dependent upon the user's selection(s). However, when I click the New button, I get the following error:
Visualforce Error
System.NullPointerException: Attempt to de-reference a null object
Class.VF_AcctNewCreate.__sfdc_TypeOutput: line 26, column 1
Class.VF_AcctNewCreate.__sfdc_SFId: line 15, column 1
Can anyone help explain why?

Try using the "getVariableValue" method of the Flow object:

Thanks Andy. I did try that (uncomment lines 28 and 29 above) but I still get the same error. Any idea why?
Andy Boettcher
Do you have the variables defined as "OUTPUT" or "INPUT/OUTPUT" in your Flow?
John Neilan 2
They are both Input/Output.
